FRAME FOR PUNCHING AND SHEARING MACHINES.

Application filed February 14, 1927.

The invention relates to frames particularly designed for use in connection with punching and shearing machines and comprising essentially connected parallel plates with a space therebetween for receiving the operating mechanism.

It is the object of the invention to obtain a rigid construction which avoids all possibility of shifting or loosening of the ele ments under the vibration and stresses to which the frame is subjected. To this end the invention consists in the peculiar construction as hereinafter set forth.

In the drawings;

Figures 1 and 1 are respectively a side elevation and horizontal section through a frame embodying my improvement.

Figures 2 and 2 are similar views of a frame particularly designed for bar cutters and angle iron cutters.

Figures 3 and 3 are similar views of a frame designed for a combination punch shears and bar cutter.

Figures 1 and 4: are respectively a side elevation and a vertical cross section of a frame for shear.

Figures 5 and 5 are views similar to Fig ures 1 and l of a slightly modified construc tion.

In all of the various modifications two plates A and A parallelly arranged are connected to each other by a spacer B which is marginally welded to said plates as indicated at C and C.

lVith the construction shown in Figures 1, 1 the parallel plates have opposite cut away portions D and one of the spacers B is fashioned to extend around this cut away portion and also along the edge of the plates below the same being secured by welding. A straight spacer plate B extends between the plates adjacent to the opposite edges thereof and is similarly secured. In Figures 5 and 5 the construction is similar to that shown in Figures 1 and 1" with the exception that the cut away portion 'D is surrounded by a U-shaped member E which is of greater width than the spacin of the plates so as to project beyond the latter. This member E is, however, welded to the margins of the plates as indicated at F.

lVith the construction as shown in Figures 4 and 4 instead. of forming a hollow mem- Serial No. 168,157.

her the parallel plates G and G are arranged offset but overlapping each other and. are connected by a solid spacer H which is marginally welded to said plates. This construction is particularly designed as a frame for shear.

The other modifications are all similarly formed but are designed for different specific purposes.

What 1 claim as my invention is:

1. A frame for punch presses and the like comprising a pair of plates parallelly arranged in spaced planes and of spacers intermediate said plates so continuously marginally welded thereto as to be integrated therewith and furnish sufficient union of the parts.

2. frame for punch presses and the like comprising a pair of plates parallelly arranged in spaced planes and a spacer between said plates adjacent to the margins thereof and so continuously marginally welded thereto as to be integrated therewith and furnish sullicient union of the parts.

3. A frame for punch presses and the like comprising a pair of plates parallelly ar ranged in spaced planes and spacers between said plates adjacent to the opposite marginal edges thereof and so continuously marginally welded thereto as to be integrated therewith and furnish suificient'union of the parts.

4%. A frame for punch presses and the like comprising a pair of plates parallelly arranged in spaced planes and having registering cut away portions and a spacer following the contour of said cut away portions and so continuously marginally welded to said plates as to be integrated therewith and furnish sufficient union of the parts.

5. A frame for punch presses and the like comprising a pair of plates parallelly arranged in spaced planes and provided with registering out away portions, a spacer fol lowing the contour of one marginal edge of said plates and also that of the cut away portion, and a spacer adjacent to the opposite edges of said plates, said spacers being so continuously marginally welded to the plate as to be integrated therewith and furnish sufficient union of the parts.

In testimony whereof I affix my signature.

ALBERT HAPPEL.
